In reply to GM4CFS:
Whilst I’ve not done Ben More I’ve got it on the immediate to do list should we get a sunny weekend before the frosts come. What I can say is that the Benmore Farm route climbs 1000m in 3000m. Which I think is classed as “unrelenting”. You can also start at Benmore Farm and continue to the end of the track by Benmore Burn and then head East up the slopes to the Bealach-eadar-dha Beinn and thence up the South face of Ben More. My Anquet route for that says 1024m climbed in 5kms which sounds better than the first route.
The other route you mention climbs out of the forest and up the Sron nam Forsairean ridge. All the reports I’ve read say the lower forest sections are very boggy and eroded. With the recent rain we’ve have it sounds like that may be a bogtastic wonderland!
You could go for the big day out and do Stob Binnein 1st then nip down to the bealach and up to Ben More. But I ran out of steam just doing Stob Binnein never mind a further 300m descent and reascent to Ben More summit.
The biggest problem is that most starting points for Ben More are around 170m and it’s 1174m high which means you’re going to climb 1000m in quite a short distance.
Robin was up there a few weeks back so he will know better. Of course I think Robin must own a pair of Nasa Technotrousers (http://www.unmannedspaceflight.com/index.php?s=dfdefb7697702bc2ba51fc188fc90780&act=attach&type=post&id=4394) judging by how he romps up the hills!
